Debugging with Android native library

To figure out the function that your native library crashed within, use arm-eabi-addr2line which comes with the Android NDK.

How to use:
1. PATH_TO_ARM_EABI_ADDR2LINE/arm-eabi-addr2line -C -f -e libXXX.so
2. type in the address to look up (the address after pc in exception logs)

or in one command

PATH_TO_ARM_EABI_ADDR2LINE/arm-eabi-addr2line -C -f -e libXXX.so AddressToLookUp
